Besides these 2 ways to fill the board, you can fill the boeard with N'Zoth, the Corruptor or N'Zoth, God of the Deep  or Bloodreaver Gul'dan. Besically this deck has 5 ways to fill the board.

How to play?

First of all mulligan hard for plot twist and dorian. Remove all other cards.

Turn 1-4:

You will start the game just like you play Handlock. Keep drawing cards until your handsize is about 9. Also early threats can be eliminated with: Defile, Shadow Bolt, Dark Skies and Hellfire. Another great protection on turn 4 isCircus Amalgam.   

Turn 5-7:

T5. Turn 5 is a bit of a weak turn. Mostlikely it is hero power and than either Shadow Bolt or Dark Skies but sometimes you need to play Zilliax.

Until turn 6 you will need to play a bit defensively, removing threats, playing taunt minions etc.

T6. Turn 6 is best for Khartut Defender or Mechanical Whelp  or Sylvanas Windrunner  and if you really need the protection: Aranasi Broodmother. Whatever you do: do not play: Dr. Morrigan on turn 6 if you do not need to. Actually it is best to play her after you have summoned a copy by either 1 of the plot twist combos mentioned above. Having multiple Dr. Morrigans is a great way to cycle cards from your deck to the board.

If you play against slower decks it is a great moment to play Deck of Chaos. A great card to make the more expensive minions cheaper.  

T7. If you have it by now: play Dorian - Plot Twist combo. If you do not have the Dorian - Plot twist combo for turn 7 keep playing defensively.

Turn 8-10:

If you managed to get the turn 7 combo, it does not really matter what you play on turn 8. Best thing to do is prepare for the turn 10 Betrug combo. If by now your handsize is below 8 try to build it up again till 9. Not playing anything here can be often a good option as your opponent is struggling with you board anyway.. 

If you did not manage to get the turn 7 combo, taunts or big threats such as Sylvanas Windrunner and Enhanced Dreadlord can be played here to ad value to N'Zoth, the Corruptor .

If you do not have the turn 10 combo late game it is best to keep pressure with Bloodreaver Gul'dan or N'Zoth, the Corruptor . It does not matter if you wont create a full board with these cards as the minions they will summon are already big threats on their own.
